[vtkusers] Intersecting curve coordinates of Clipping polydata

[Jianlong Zhou]

Hi, all,

I have a problem: I use vtkClipPolyData and vtkClipVolume to clip a 
surface and a volume respectively. The clipping implicit function is 
a sphere. So the intersecting curve between sphere and the clipped 
surface is a spatial curve. I want to locate this curve and want to 
use the points coordinates information and attributes on this curve. 
How can I locate the intersecting curve and its points coordinates?
Thank you for your help.

Best regards.
